You're probably reading this because you don't want to sink time or money into proprietary protocols and agents anymore. Why would you? They tie you to a single vendor, force you to adapt to their quirks, and make it painful to change direction later.

What you really need is an open, consistent way to instrument, collect, and move your telemetry without worrying about compatibility or lock-in. That's exactly what OpenTelemetry (OTel) gives you. And at the center of it all is the OpenTelemetry Protocol (OTLP), the common language that makes your services, collectors, and backends speak fluently with each other.

This guide will walk you through OTLP in detail: what it is, why it matters, and how to use it in real pipelines. By the end, you'll see how embracing OTLP and pairing it with an OTel-native backend helps you solve the challenges of modern observability while keeping your stack open, reliable, and free of lock-in.
